A Study On The Problems And Countermeasures Of Scale Economy Of Marine Aquaculture In China

The general guiding ideology in twenty-first Century China’s mariculture layoutis the implementation of ecological engineering breeding strategy, to promote thehealthy development of industry. However, the general characteristics of marineaquaculture industry layout has the resources oriented, discrete space and weakindustries such as agricultural layout, so that the marine aquaculture resource spacewith regional distribution, to a certain extent it leads to the problems of ecologicalenvironment in the vicinity of the mariculture areas. Therefore, how to use modernbiology and biotechnology and engineering technology, coordination of therelationship between aquaculture and aquaculture environment, achieve thesustainable development of aquaculture industry, has become an important issue ofconcern in theory and in practice.This topic takes marine aquaculture as the research object, based on the basis ofthe theory of industrial ecology, economy of scale, industrial economics. On thepremise of the development of marine aquaculture in our country, analysis theindustry trend of aquaculture development of scale economy in recent years, surveythe problems on the conservation of the living marine resources, ecological andenvironmental protection economic benefit, technological innovation, industrialmanagement aspects of mariculture industry, according to the basic principle of thefour modernizations synchronization, explore the logical mechanism of aquacultureindustrialization development and implementation path.The modern aquaculture is the specific direction of aquaculture industryupgrading, and the development of scale economy is an inevitable path to achieve thegoal of mariculture.Theory of industrial ecology, industrial relationship theory, andindustrial structure theory is the theoretical basis for aquaculture development of scaleeconomy. In theory, marine aquaculture industry scale economy pattern includesaquaculture, marine cage aquaculture, mariculture, offshore raft cultivation, shallowseabed sowing breeding. The development of mariculture involving the environment,resources, market, technology, investment, policy and other aspects, the developmentof economy of scale must co-ordinate arrangements, system consideration, scientificplanning. Since the reform and opening up, the sea farming industry in China has madegreat achievements, variety structure, area of cultivation, aquaculture production,aquaculture production statistics of mariculture, shows the mariculture industry inagricultural economic development, improve dietary structure, increase the income offishermen, technological progress, adjust the industrial structure of marine fishery andother aspects of the impressive performance, but at the same time China’s mariculturein aquaculture environment, marine disasters, industrial structure, water qualityproblems.By other’s faults, wise men correct their own. From the point of the whole world,aquaculture has become an important way to meet the demand of high quality proteinof human growing. A common practice in developed countries aquaculture fisheriesdevelopment of scale economy is: the importance of marine biological resourcesconservation; ecological protection is the core of development of mariculturemariculture; improving scale benefit innovation culture; indispensable supervisionand support of the government. These practices have pointed out the direction ofChina’s marine aquaculture industry economies of scale: actively promote the watersand tidal land planning and culture planning work; strengthen the government publicservice function of Mariculture Development of scale economy; the integration ofscientific research resources, providing technical support for the marine aquacultureindustry economies of scale; to carry out targeted fishery resource enhancementactivities.Since the reform and opening up, China’s mariculture actively explore theeconomies of scale: our country begins to pay attention to aspects of marine fisheryresources and ecological and environmental conservation industry development;through the breeding of varieties to promote aquaculture development in scale;continuous improvement, innovation culture mode, improve aquaculture scale benefit;give full play to the role of technology in aquaculture scale management supportingrole in disease prevention and control; reduce the aquaculture scale operation risk;farming mechanization, digitalization has become the new power sea farming scalemanagement. But there are major problems in economic benefits, seed cultivation,breeding, disease prevention, farming mechanization of Digital China’s MaricultureDevelopment of scale economy, affected the development of mariculture high-end.To correctly judge the seawater aquaculture scale benefits analysis scaleefficiency. This paper introduces the basic theory of DEA method, constructing the mariculture scale efficiency model of our country, establish the mariculturemanagement scale efficiency evaluation index system, variables selection, dataprocessing, and finally the use of DEA method to analyze the efficiency ofChina’s mariculture, determined the mariculture optimal efficiency scale. The resultsshow that, the low level of aquaculture technology is the main cause of our currentaquaculture scale difference. The short term, China’s mariculture should moderatescale management, focus on improving the technical level of aquaculture, improvecapital, fry, mariculture area scale production efficiency. In the long run, changeshould implement the mariculture from labor-intensive to capital and technologyintensive industries, promote aquaculture scale efficiency, achieve economies of scale.Ecological industry, equipment engineering, technology modernization, factoryproduction, management industrialization is China’s Mariculture Development ofeconomy of scale in the future direction, and accordingly, industrial farming hasbecome the inevitable choice of current China’s Mariculture Development of scaleeconomy. Therefore, China’s Mariculture Development of economy of scale andspecific measures to improve the scale efficiency is: industrialization to promoteprimary measures of aquaculture development of scale economy. Secondly, makesustainable aquaculture development of economies of scale to promote technologicalinnovation. Third, improve the financial service system; provide a stable source offunding for the aquaculture development of economy of scale. Fourth, the use ofindustrial management concept, improve aquaculture scale efficiency.
